Does LCD need PWM?
PWM is a very rapid frequency of on/off states of the digital signal to achieve a result similar to what could be achieved on a plain Analog signal. PWM is used not only for LCD monitor brightness, but most forms of finite control in electronic devices today.

How do I know if my LCD is 16X2?
HOW TO CHECK WHETHER 16X2 LCD WORKING OR NOT
- Are you worried whether your 16×2 Lcd is working or not?
- >> Connect the pin vcc pin to 5v.
- >>Connect pin Vee and gnd pin to ground.
- >> Connect Led+ to 5v.
- >>Connect led- pin to ground.
- If your Lcd is not working well, then both the lines will be bright shown below.
Is my screen PWM?
What to look for? Depending on how you see the moving line you can determine if your monitor uses PWM to control the brightness. You can test this by setting your hardware brightness to 100%. When your hardware brightness is set to 100% your monitor doesn’t use PWM in all cases and you should see this smooth line.
